`bootc install to-*` needs a network connection to run even when the image is already on storage

At least on the containers-storage transport, it seems that bootc install absolutely requires a network connection due to it checking the remote instead of checking local storage first.

Here is an example:

$ bootc --version
bootc 1.1.6

# heres my containers-storage
$ sudo podman images
REPOSITORY                TAG         IMAGE ID      CREATED       SIZE
ghcr.io/ublue-os/bluefin  beta        43f35a4d4153  46 hours ago  7.55 GB


# no network connection, running bootc install on the host directly 
$ sudo bootc install to-disk --source-imgref=containers-storage:ghcr.io/ublue-os/bluefin:beta /dev/vda --filesystem btrfs --wipe
ERROR Installing to disk: Verifying fetch: Creating importer: failed to invoke method OpenImage: failed to invoke method OpenImage: pinging container registry ghcr.io: Get "https://ghcr.io/v2/": dial tcp: lookup ghcr.io: Temporary failure in name resolution

# whenever i connect to a wifi or something, it just works 
$ sudo bootc install to-disk --source-imgref=containers-storage:ghcr.io/ublue-os/bluefin:beta /dev/vda --filesystem btrfs --wipe

I am testing this from a beta Bluefin live ISO, but this environment shouldnt be any different than running this directly on any host system. Here is the ISO if anyone wants to test this directly where I am also testing it: https://download.projectbluefin.io/bluefin-live-stable.iso

Could you try to add --skip-fetch-check to see whether it helps?

Yes, we also just changed this in #1256 so closing as fixed by that PR, but feel free to reopen if you find otherwise!
